Developping for Android [Tutorials]

Hello, sure that i'm not the only one who realized that pc games aren't simple anymore, to make a pc game succeed, you need Battle Field graphics, however, on the Android/iOS, simple game are still successful (doodle jump!!!!)

so first i started reading the ebook (Beginning 3D Game Development with Unity by Sue), but unfortunately, i don't agree with her in many things.

Anyway, i'm looking for some tutorials/ebooks for unity that are for developping an android game, because you know, the inputs and controls are so different, and i'm kinda lost here

Thank you , looking forward for your answers :p
